Multi-Contact makes MC4 "sealing caps" but I have not been able to find them
for sale in the US. Maybe you will have better luck. Plastic and
electrical tape has had to suffice for us until a better solution is more
available. If you found a good plug I suppose you could also just use spare

We make flexible cable assemblies for a local track rack manufacturer. seems last winter gremlins convinced "us" to muff up a large order (transposed MC4 connectors). We repaired things by pruning off the wrong polarity connectors. so, we now have we have boxes of made up MC4 connectors looking for
Hi wrenches;
SolaDeck Models 0760-41AD and 0766-41AD are rated for up to 60A at 240Vac.
It can be ordered with DIN rail mounted AC breakers and a combiner kit.
The 2 - 20A circuit combiner kit is part 0760K2AC.
I'd recommend checking with a distributor or on SolaDeck's website for the
most curre
NICK:
I could not find the AC model numbers you provided on the
SolaDeck web site. Do you know the
manufacturer, and the voltage and
temperature ratings, for the 2-pole 20A AC breakers?
I just called Soladeck and they are sending me some more info on
availability. I'll pass it along when I get it. I didn't realize they made
an AC roof mounted string combiner solution. That's a huge help for 2 or 3
string Enphase installations (they make both combiners).
While on the subject, we r
I did get some pictures and info from Soladeck. Here are some links:

Friends:
We have one site that is experiencing ongoing problems with errors
indicating, "AC Voltage Out Of Range." This has occurred on two of 17 M190
inverters. Apparently the voltage is not really out of range, the inverter
is erroneously reporting.
I have one replacement in hand and was
On one installation, I had the same error cod issue. The project also used
the M190 inverters. The issue ended up being a loose connection between one
of the inverter-to-inverter connections. After re-checking all of the
connections, and making sure the connection was tight, the error code did

Hi William,
We have experienced this at one installation using 22 M-215's. There is
not yet a conclusion, but here are some things worth looking out
for.I printed out a spreadsheet of the incidents and noticed over a
one month period that they were all happening at either 8:30 am or 1

JASON:
I talked to Steve Capozzi of SolaDeck and he sent me additional info
about the circuit breakers:
_Manufacturer_: ABB
_Terminal Temp Rating_: 75C / 167F
_Reference Temperature_: 20C / 68F
_Ambient Temp Derating_:
30C/86F = 18.7A
40C/104F = 17.3A

Wrenches,
We keep a supply of MC4 caps on-hand for this purpose. Purchased from
Kensington Electronics (keiconn.com). You may try pv-cables.com, too.
MC Type and Order Number respectively:
PV-BVK4 / 32.0716 (f)
PV-SVK4 / 32-0717 (m)

Dear Wrenches
I've been experiencing a troubleshooting problem that you may be able to
help me with. Or, can anyone refer me to someone, maybe an electrical
engineer?, who I could hire to help.
About 7 years ago I installed Unisolar modules on all the roofs of a complex
of 12 mixed use buildings
Not to be too nit-picky, but I think its a good idea to distinguish between
branch circuits (parallel connections) and strings (series connections).
Enphase inverters are wired in parallel while string or central inverters
require modules to be wired in series (with parallel strings as an
option).
Have you tried a megger? The 1,000v setting should display any breakdown
areas.

If you're in Sebastopol you could ask Paul Hernday at Solmetric if the PVA
would help.

Hello Wrenches,
I am in need of an analysis for a large battery backup system. I am
looking for a sweet spot in PV array size and battery bank size. I need
this modeled on a time of day basis, and evaluated monthly thru a full
calendar year. I am told that PVSYST can perform such an analysis bu
